Abstract (en)
An Integrated Digital Network (IDN) includes a matrix and usersignal ports for exchanging voice, data, IDN control, and building control digital signals between the matrix and user equipment, the digital signals comprising single samples of each signal type from each user port in each IDN sample time interval, the IDN further including a transmission system for concentrating user port digital signal samples of each sample time interval, by common signal type, into multiple bit channel signals for exchange between the user ports and matrix signal ports of the matrix switch, the matrix switch interconnecting each channel signal from one or more user ports to one or more other user ports.
